It is recommended that wireless networks use WPA-PSK, WPA, or stronger
encryption. IEEE 802.1x and WEP encryption are better than none at all, but it is
still possible for unauthorized devices to figure out the original information
pretty quickly.
It is not possible to use WPA-PSK, WPA or stronger encryption with a local
user database. In this case, it is better to set up stronger encryption with no
authentication than to set up weaker encryption with the local user database.
When you select WPA2 or WPA2-PSK in your P-660HWP-Dx, you can also select an option
(WPA compatible) to support WPA as well. In this case, if some wireless clients support
WPA and some support WPA2, you should set up WPA2-PSK or WPA2 (depending on the
type of wireless network login) and select the WPA compatible option in the P-660HWP-Dx.
Many types of encryption use a key to protect the information in the wireless network. The
longer the key, the stronger the encryption. Every wireless client in the wireless network must
have the same key.
7.3.5 One-Touch Intelligent Security Technology (OTIST)
With ZyXEL's OTIST, you set up the SSID and WPA-PSK on the P-660HWP-Dx. Then, the
P-660HWP-Dx transfers them to the devices in the wireless networks. As a result, you do not
have to set up the SSID and encryption on every device in the wireless network.
The devices in the wireless network have to support OTIST, and they have to be in range of
the P-660HWP-Dx when you activate it. See
7.4 General Wireless LAN Screen
Use this screen to configure your wireless settings.
If you are configuring the P-660HWP-Dx from a computer connected to the
wireless LAN and you change the P-660HWP-Dx's SSID or WEP settings, you
will lose your wireless connection when you press Apply to confirm. You must
then change the wireless settings of your computer to match the P-660HWP-
Dx's new settings.
